UNITED STATES PATENT JOHN KLUENTER, OF ALLENTOW'N, PENNSYLVANIA.

WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,551, dated November 5, 1889. Application filed October 17, 1888. Renewed October 5, 1889. Serial No. 326,072. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN KLU ENTER, a citizen of the United States, residing at Allen town, in the county of Lehigh, State of Pennsylvania, have invented certain new and useful Improvements in WVood-NVorking Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to wood-Working machines of that class known as channeling, and is especially designed for facilitaiing the formation of acertain form of channel employed in the sliding sections of win (low-frames for which United States Patent No. 206,181 was granted me on the 23d day of July, 1878,

Among the principal objects in view are to provide a machine adapted to receive a section or strip of wood and by a single passage through the machine of the strip to form a peculiar-shaped channel for the reception of asimilarly-formed connecting device, all as hereinafter described.

Referring to the drawings, Figure 1 is an end elevation of a machine constructed in accordance with my invention. Fig. 2 is an enlarged view in end elevation of the channelcutters, and Fig. 3 is a side elevation of the same.

Like numerals of reference indicate siu1ilar parts in all the figures of the drawings.

In the patent above referred to the opposite faces of the sliding sections of the windowscreen frame are provided with opposite reg istering dox' etailed grooves adapted each to receive one-half of a metallic substantially Xeshaped connecting device which maintains said sections in sliding contact, whereby the screen'frame may be enlarged or extended or the sections slid one upon the other, and thus reduced in width, whereby different-sized windoor-frames may be fitted.

1 represents the base of the machine, which is provided with oppositelongitudinal and adjustable L-shaped guides 2, regulated by setbolts 3, passing through the same and into the base. At that portion of the base 1 where it is desired that the operation of channeling or cutting shall take place I provide diagonallyoppositc standards at, one arranged in rear of the other, and each provided with upwardly and outwardly extending supplemental bearing-frames 5, terminating in bearing-boxes 6, inclined to such a degree as to be adapted for 5 5 receiving a cross-shaft 7,.the ends of which are mounted in the said boxes. Upon this cross-shaft is a belt-pulley 8, carrying a belt 9, which transmits power to the machine and rotates with the shaft opposite gears 10, mounted near each end of the shaft 7. At the inner corners of the standards a are provided thereupon journal-boxes 11. These boxes are in line with their respective standards, and, as before stated, the standards are mounted one in front of the other, or, in other words, out of alignment. Therefore the shafts 12, which are inclined downwardly and mounted in said boxes 11, are out of alignment with each other, the one being arranged 7c in front of the other.

The shafts 12 extend beyond the rear end of the boxes 11 and terminate in supplemental boxes 13, which are formed in the supplemental bearingarms 5 below the boxes 6, and mounted upon the shaft, intermediate its two bearing-arms 11 and 13, are beveled gears 14, which mesh with the superimposed gear 10, mounted on the shaft 7.

The shafts 12 are of such a length as to pass each other near their lower ends, and are provided at those ends with beveled cutters or channelers 15 of the same size, as clearly shown in Fig. 2.

The operation of my invention is as follows: Motion is imparted to the shaft 7 and its gears 10 through the medium of the belt 9 and the pulley 8, and is transmitted from the gears 10 to the beveled gears 1t and from them to the inclined cutter-shaft 12 and cutters 15. These being set in n1ot-ion,a strip 16 is in- I sertcd between the guides 2, and may be fed automatically or by hand to the cutters, whichby reason of their relative arrangement. will form a dovetail groove or channel 17, as. 9 5 shown in Figs. 1 and 2. Two of these strips connected by means of the metallic connection described, it will be apparent, are maintaiued in sliding contact with each other.

Although I have herein described the ma- 1C0 chine as designed for cutting dovetails in a certain form of windowscreen rails, it is apparent that the same may be employed for other wood-worksuch as, for instance, in tables, sliding blinds, &c.

Having described my invention,wl1at I claim 1s In a machine of the class described, the diagonally-opposite standards 4, having the oppositely-inclined parallel bearings 11 and the upwardly-projecting arms 5, having the bearings 13, in line With the bearings 11, and having the diagonal bearings 6 at their upper ends, in combination with the parallel inclined shafts 12, mounted in the bearings 11 and terminating in the bearings 13, and provided and having the gears 10, meshing with the gears 14:, and having the pulley 8, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN KLUENTER. \Vitnesses:
